Introduction: The 12-lead ECG at admission of patients suffering from acute myocardial infarction (AMI) is mandatory for accurate diagnosis and prompt therapeutic measures, mainly reperfusion. It has been shown that recording additional ECG leads may improve the diagnostic accuracy and therefore, the prognosis of selected cases. Aim: The aim of the study was to assess the usefulness of the 15-lead ECG (12 classic plus 3 posterior leads) in the management of chest pain patients, especially when 12-lead ECG is not diagnostic of AMI. Methods: Total amount of 186 consecutive patients (127 men, 59 women, mean age 69.7±13.8 years) were admitted with an acute coronary syndrome. The initial ECG recorded the 12 classic leads, and subsequently, the 3 additional posterior leads. Demographic and clinical data, including ECG alterations and selected treatment strategy, were also studied. The cumulative impact of the 15-lead ECG on the diagnosis and management of AMI were, overall, evaluated. Results: The 12-lead ECG was diagnostic of ST-elevation AMI (STEMI) in 158 patients (Group A–84.5%) who were promptly reperfused. On the other hand, the interpretation of the posterior leads was required in 28 patients (Group B–15.1%) to establish the STEMI diagnosis warranting reperfusion therapy. Multivariate analysis illustrated that the 15-lead ECG was the only factor associated with achieving the STEMI diagnosis in non-conclusive 12-lead ECG cases (OR=2.43–p=0.04). Conclusion: The use of the 15-lead ECG contributes to a faster and more accurate diagnosis of STEMI, particularly in the Emergency Department, facilitating the prompt reperfusion therapy.
This study was conducted to investigate the effect of four blossom honey types (orange, chestnut, heather and cotton) on a group of quality characteristics of thyme-type based mixture preparations. Mixture ratios were prepared at 0%, 50% and 100% per blossom honey-type and then were blended with thyme honey in parts 1:1. The melissopalynological, sensory and physicochemical quality characteristics for each blend were monitored. A three-level, four-factor orthogonal array according to the Taguchi method was utilised to plan the experiments maintaining the thyme component as a 'slack-variable' to contain the number of performed trials. Subsequent anova treatment revealed that only a pure orange-type blend favours the simultaneous maximisation of aroma (P < 0.05) and the minimisation of electrical conductivity (P < 0.05). Finally, there was a significant effect of chestnut-type blend content on microscopical and physicochemical characteristics (P < 0.05), nevertheless, their corresponding signal-to-noise ratios are maximised only at a concentration of zero value.
Introduction: Transesophageal overdrive pacing is an accepted method for the diagnosis and treatment of supraventricular tachycardias, although is not used frequently in clinical practice. Case report: A 47 years old woman is reported with a medical history of β -Thalassemia Major admitted to our hospital with atrial tachycardia of recent onset and successfully converted using a transesophageal overdrive atrial pacing. Conclusion: Transesophageal overdrive atrial pacing is a low cost, simple and safe procedure that can be performed at the bedside, especially in patients, as those with β -Thalassemia Major, whose health status makes difficult the usage of medicines that could possibly aggravate their general health status.
Introduction: Spontaneous dissection of the coronary arteries is relatively rare and usually does not affect life expectancy. However specific types have been implicated to episodes of sudden cardiac death and myocardial ischemia. The recognition of both clinical and imaging characteristics contributes to appropriate decision and patient management. Aim: The aim of the study is the epidemiological and Coronary Angiographic (CA) estimation of patients with spontaneous dissection of the coronary arteries, who were hospitalized in the cardiology department with Acute Coronary Syndrome or were submitted to coronary angiographic examination in the laboratory. Material and Methods: The epidemiological, clinical and angiographic data of 31 patients who were hospitalized in our department and suffered from spontaneous dissection of the coronary vessels were studied retrospectively. Results: In 31 patients (11 men and 20 women, mean age 52.8+18.6 years) who were hospitalized for acute coronary syndrome (ACS), spontaneous dissection of coronary arteries was detected. Precipitating factors were hypertension in 12 patients (38.71%), dyslipidemia in 13 patients (42%) and smoking in 17 patients (54.84%). Among the women, 13 (65%) had a history of hypertension in pregnancy, preeclampsia or/and gestational diabetes. In 8 patients, the coronary angiography showed multivessel disease, while in 12 patients there were no significant lesions in the coronary vessels. Fourteen women (70%) reported a history of depression compared to none in men. Conclusion: The incidence of spontaneous dissection of the coronary vessels in this sample of patients from northern Greece is similar to that of the other centers. The incidence is greater in females with hormonal changes and depression. In a large number there were no significant atherosclerotic lesions.
